A major aluminum advantage is its weigh/ mechanical resistance ratio, as well as its endurance.

Thanks to these features, aluminum is more and more used in the transport industry. 

The use of aluminum profiles in the automotive industry (cars and commercial vehicles) and in the naval, railway and air transport industry is encouraged by the increasing need to reduce expenses and to transport heavy weights.   

The railway transport industry considers the use of extruded aluminum for railcars a successful choice also because of the profitable relationship between costs and light weight.
